Claims.

1 The invention relates to a safety attachment for stoves and especiallyan attachment which will act as a guard for preventing the accidentalturning, or turning by children, of the handles to the valves whichcontrol the supply of fuel.v

such guards, although it may be applied to new stoves.

The attachment can best be seen and understood by reference to thedrawings in which it is illustrated as applied to guard the handles 'ofvalves which control the supply of fuel to an oil range, and in whichFig. 1 is a view in front elevation of a guard so applied, one of theguards being shown moved to an open position by which access may be hadto the handle, normally enclosed by the guard,

for turning it.

Fig. 2 is a view in rear elevation; and

Fig. 3 is a section on the line 3-3 of Fig.1.

Referring to the drawings: l represents a pipe fixture, with which thestove is ordinarily equipped, bearing a dial plate 2 over which turns ahandle 3 for controlling by its turning a fuel supply valve (not shown).

In practice two handles are employed for controlling separate valves.

The present guard attachment comprises an apertured base portion 4 withremovable cap 5 which together enclose a handle 3 upon the applicationof the base portion of the attachment to the outer face of the dialplate in surrounding relation to the handle.

The top of the cap is preferably made of some transparent materialthrough which the handle and any indications on the dial plate may beseen when the cap is closed. The cap may be secured to the base portion4 of the attachment in any suitable manner. As shown it is securedthereto by a hinge connection 6 including a hinge pin l on which isarranged a coil spring 8 with ends bearing, respectively, against theside of the base portion and that of the cap and by which means the capis held normally closed.

The guard attachment is detachably secured to the dial plate in thefollowing manner. Formed within the base portion 4 of the attachment andleading from the outside to the interior thereof are slots Ill, ill.Each of these slots is a relatively wide slot of some considerablelength but of little depth or thickness. Inserted from the outside andslidable within these slots are 2 clips ll. Each of these clips, angularin form, comprises a leaf I2, sliclable into and out of the slot Illwithin which it is contained, and on the outer end of this leaf, outsidethe base portion '4, an angularly turned leaf l3 which laps by the edgeof the dial plate, the two leaves thus occupying an overlapping andunderlapping relation to the edge of the dial plate.

The two clips are drawn into engagement with the opposite side edges ofthe dial plate by means of springs l5, l5, which extend, respectively,on opposite sides of the pipe fixure l, and the ends of the springs aresecured, respectively, to the angularly turned leaves I3 of therespective clips. The pull of the springs when tensioned will then actto draw the clips into engagement with the opposite side edges of thedial plate. The extent of their movement in attaining such end willdepend upon the size of the dial plate, the socketing of the clips withslidability in their sockets, and the tensional control exerted by thesprings admitting of considerable adjustable variation in accomplishingthis end. The springs when under tension holding the clips in place willbear, respectively, against the opposite sides of the pipe fixture I asshown in Fig. 2. The pipe fixture will then act to prevent lateraldisplacement of the springs and that of the entire attachment, the samebeing held fixedly in place.

The guard presents an attractive appearance and adds to the finish ofthe stove.

I claim:

1. An attachment of the type specified for guarding a valve controllinghandle associated with a dial plate over which the handle turns,comprising an apertured base portion with removable cap adapted toenclose the handle upon the application of said base portion to theouter face of the dial plate in surrounding relation to the handle, thebase portion having sockets therein extending, respectively, from theoutside to the interior thereof, clips movable within said sockets tohave drawing engagement, respectively, with opposite side edges Of thedial plate with overlapping and underlapping relation thereto when theclips are moved to engage said edges of the dial plate, and meanswhereby said clips may be made to have engagement with the dial plate asaforesaid.

2. An attachment of the type specified for guarding a valve controllinghandle associated with a dial plate over which the handle turns,comprising an apertured base portion with removable cap adapted toenclose the handle upon the application of said base portion to theouter face of the dial plate in surrounding relation to the handle, thebase portion having sockets therein extending, respectively, from theoutside to the interior thereof, clips movable within said sockets tohave drawing engagement, respectively, with opposite side edges of thedial plate with overlapping and underlapping relation thereto when theclips are moved to engage said edges of the dial plate, and meansconnecting said clips by which they are moved to have engagement withthe dial plate as aforesaid.

3. An attachment of the type specified for guarding a valve controllinghandle associated with a dial plate over which the handle turns,

comprising an apertured base portionwith. re-

movable cap adapted to enclose the handle upon the application of saidbase portion'to the outer face of the dial plate in surroundingrelation. to the handle, the base portion having sockets thereinextending, respectively, from the outside to'tl'le'interior thereof;angular clips applied from outside-of said base portion and movablewithin thesockets therein to have drawing engagement, respectively, withopposite side edges of the dial plate with overlapping and underlappingrelation thereto when the clips are moved to engage said edges of thedial plate, and resilient means connecting said clips by connection withangularly turned parts thereof wherehythe clips will be held to haveengagement with the dial plate as aforesaid.

4. An attachment. of the type specified for guarding a valve controllinghandle associated with a dial plate over which the handle turns andwhich dial plate is borneby a pipe fixture extending-rearwardlytherefrom, said attachment comprising an apertured baseportion withremovable ca-p applied to said. dial plate and enclosing said handle,said base portion of the attachment having sockets therein extending,re-

spectively, from the outside to the interior thereof, clips movablewithin said sockets to have drawing engagement, respectively, withopposite side edges of the dial plate with overlapping and underlappingrelation thereto when the clips are moved to engage said edges of thedial plate, and means held against lateral displacement by said pipefixture connecting said clips and by which they are moved to haveengagement with the dial plate as aforesaid.

5. An attachment of the type specified for guarding a valve controllinghandle associated with a dial plate over which the handle turns andwhich dial plate is borne by a pipe fixture extending rearwardlytherefrom, said attachment comprising an apertured base portion withremovable cap applied to said dial plate and enclosing said handle, saidbase portion of the attachment having sockets therein extending,respectively, from the outside to the interior thereof, clips movablewithin said sockets to have drawing engagement, respectively, withopposite side edges of the dial plate with overlapping'and underlappingrelation thereto when the clips are moved to engage said edges of thedial plate, and springs connecting said clips to have engagement withthe dial plate as aforesaid, said springs being arranged onoppositesides of said pipe fixture whereby they will be held thereby againstlateral displacement.
